PROTEQTING DEVICE FOR TIRES.

No. 890,785. A Specification o Application filed January and puncture and reducing Wear.

Various devices have been provided for similar purposes, and the principal objects of this invention are to provide simple and efhcient means for accom lishing these results, and to afford additional) protectionto' the tire the same being carried out by the use of a series of plates having wearing surfaces preferably provided with projections, and the attachment of these plates tothe tire in such a manner as to prevent their accidental detachment therefrom.

The invention j also comprises a novel method of produc'ng the tire.

` Further objects vention will appear hereinafter.

Reference is to be had to the accom anying drawing" which illustrates certain forms in which the invention'may be embodied, .and in which Figure 1 is a transverse sectional view of a portion of one form of the outer tire or shoe showing the anti-skidding plates in position. Fig.- 2 is a'similar view of the complete outer tube. Fig/3 is a plan of a portion of a tire showing another form of the invention'. Fig. 4 is a longitudinal section of the same on the line 4 4 of Fig. Si Fig. 5 is a plan of a modification. Fig. 6 is a transverse sectional view of the form shown in Fig. 5. Fig. 7 is a similar view showing a modification'comprising a fastening device which c'an be employed, and Fig. S is a longitudinal section of'the same.` l'

In carrying out this invention the wearing surface of the-tire is provided with a plurality of plates a, a2 or a3 which `may extend-transversely or obliquely,v as shown in Fig. 4, and whichlmay be eitri'er smooth or rough on their In the form* shown in Figs. 3 and 4 they are` provided with projections af, while 'in the form shown in Figs. 5 and 6 the plates a4 are corrugated on their wearing suraces.

In the form .shown in Figs. 3 and4 the wearing plates a72 are shown disposed in oblique. position, and in order to break joints j two of the lates a2 are shown located adjacent to eac other, forming a `V, and alter- I nating with These plates Fig. 6, or in any other desired "way to accomplish the same result. They may be placed upon the outside of the tire or removable shoe, but 'I prefer to embed them slightly in such position that the rubber b will extend outwardly between the `plates to form cushioning projections b. (Fig. 4) which may constitute practically continuous surfaces with respect to the plates. rated from each other affording resiliency, and the cushioning projections b are preferablyextended between the plates in order to assist in holdingthem j in position without destroying the resiliency of the tire or protecting shoe. l

In the' manufacture of the tire or-shoe, a few layers of frictioned duck -or the like are first secured together in anydesiredway to form one piece, then the plates are'- placed thereon `in` desired position -and fastened through this ieee. The fasteningfmeans Amay be' varied ut in 1, the plates are provided with e and rivets c are passed through tlhe same, thel heads of the rivets projecting from the=outer faces ofthe plates. The ends of the'rivets project inside and are ers d over Vwhich their 'forl the purpose of ends are riveted.

in the form of integraluin'wardlyfextending projections c4 on the plateswhich, can'be riveted over a single washer d or'a separate washerd for each projectionor rivet as desired. -After this much ofthe article is constructed, as shown in Fig.- 1, the same-is placed in a mold, and the remainder-of the tire or shoe applied and vulcanized thereto `to be seen that while lthe metal produce an article such as indicated in Fig. 24A

an article completed in this are resiliently supported, not being' but being separated by them are V-shapedplates a3. ff may be modified as shown in the rubber itself, that is, to place them in The plates are sepaheld in 'place-by wash- In the form shown in Fig. 6' the rivets are shoe, the rubber' and frietioned duck surrounding the same and beimr vulcanized together around them, 1t will be seen that/although they may yield as much as would be it is connected therewith at the other end of' the washer d. In the preferred forms each plate is held, as stated, by its rivets or pro- Y jections being riveted to a single washer or plate.

As so far described, the only means for preventing puncturing at )oints between the plates is the additional thickness of rubber b )eforedescribed and the ordinary protection `afforded by the shoe or the tire itself, in addition to which should be considered the protection afforded from the fact that the plates are located sufficiently near each other to prevent large pieces of glass or the like from passing far into the tire. In order thoroughly to protect the inner part of the tire or shoe, l prefer to provide additional plates c. .These plates'may bc smaller than l the plat-es c, ae, c4 or (L5 if desired but shou d be sufiiciently large to overlap the edges'thereof so as to afford lprotection for the whole of the tire. It wil be seen that bv the placing of such plates within the body of the tire or shoe and at some little distance inward from or behind the plates a, a2, c?, a* or a5 all the -protection afforded by a continuous metal outer rim will be provided for V and yet there will be no substantial reduction in the resiliency ofthe tire.

The preferred way of manufacturing the tire or shoe with these plates in position, as

indicated in Fig. 4, is first,to form two or.

more thicknesses of frictioned duck and unite the plates e to them in a manner similar to that described above, rivets Ior projections f being employed and thesey being rovided with washers g on the inner face of.) the frictioned duck. When these are in position, the outer portion of frictioned duck and rubber is applied and some inner thicknesses of frictioned duck are placed over the headed ends of the rivets'or" projections f. Then the lates a., a?, (1,3a or a5 are applied and the article completed in the manner described above.

As an additional means of securing the plates .in position, I have shown in Figs. 7 and 8 a construction in which the plates a5 are provided with perforations, these erforations being in line with each other airing the circumference of the tire, then fastening devices, preferably in the form of two or more wires lt, are threaded through the perforations and their ends secured together so as securely to hold the )lates in position. The Wires may be located on the outside'of the rubber. or embedded therein. When this forni of fastening device is used. the projections or rivets may -be dispensed with but I prefer to ret-ain them as is indicated in Fig. 7.`

Whilel I have illustrated and described certain ways in which the plates can be constructed and heldin position I am' aware that 'many modifications may be made therein without departing from the vl'scope of the invention as expressed in theclaims.

Having thus described my invention-| what I claim iszl l. In an article of the class described, the combination of a series of )lates arranged around thc `periphery thereof" on the surface of a body of yieldingmaterial, said plates being spaced apart and the yielding material extending in t 1e 'spaces between them so as to form a substantially continuous surface with them, said plates being arranged obliquely and in such manner as to break jomts, a plurality of rivets extending inwardly from each plate, andl washers enibedded within the body of yielding material and surrounded by said material, said rivets passing through the plates and having their leads on the outside of the same and constituting anti-skidding projections. 2. An article of the class described formed of resilient material and having on the wearing surface thereof a plurality of'individu-V ally supported plates separated from each other, the resilient material extending into the spaces betweenthe plates and forming cushions between them, and metallic pro- `ally supported plates separated from each a plurality of plates` entirely other, and l separated from the first named plates by; the resilient material and locatedwithin the ody of the resilient material and directly inward `from or behind the spaces between the first named plates.

4. An article of the class describe having on its surface a series of metallic plates spaced apart, means embedded in the body of the article for holding said plates in position, plates located intermediately between the first named plates and their holding means and within the-spaces between the first vnamed plates for protecting the inner portion of the article from uncture, anda ody of resilient material ocated between the outsideseries of metallic plates and said intermediate lates. y

5. An artic, e of the class described having protecting plates on its surfacespaced each other, washers Within the body of the article for holding said plates, a series of from plates located within the body of the article and back 'of the nameddplates, and

the bo 1n position.

6. Amethod described, whlc of fabric, then plateeon the ou spaces between the first means also located within of making articles of the class y layers h consists in forming placin tside O a series of metallic alternately with the 4first named plates on 15 the Outer surface thereof, placing Washers on the Inner surface th ereof and securing the Outer plates to the inner washers, placin the article thus produced in a mold resilient Witnesses material over thewashers.
